Prem's place looks better in person! There's also free access to the gym and swimming pool. It is also very near BTS Nana. Terminal 21 is just 8 minutes away. Lots of 711/FamilyMart in the area and there is also a TOP's supermarket and food court nearby.
You can also do laundry inside the condo. Overall I really loved my stay and I would really consider staying here again when I visit Bangkok :)
